Abstract: The present invention provides an array of polymers and methods of forming arrays of polymers by providing a substrate having a first layer including one or more dielectric coatings on a solid support and a second layer including a plurality of polymers disposed on the first layer. The invention also provides methods for forming an array of polymers on a substrate using light-directed synthesis by providing a substrate having a first layer including one or more dielectric coatings on a solid support, derivatizing the first layer by contacting the first layer with a silanation reagent, and a second layer disposed on said first layer wherein the second layer includes functional groups protected with a photolabile protecting group.

Abstract: Methods are provided for the preparation of polymer arrays on wafers wherein the wafers are rotated between synthesis steps to provide more uniform results across the entire wafer.

Abstract: The present invention provides methods to inspect biomolecules on a solid support using a reflectance measuring tool. In one embodiment of the invention, in-process methods are provided that analyzes wafers after specific steps of the microarray manufacturing process. In another embodiment, probe defects from handling or particulates during manufacturing of microarrays are detected by analyzing wafers and chips.

Abstract: Methods are provided for preparing nucleic acid arrays on a support, particularly substantially planar supports. In one group of these methods a plurality of nucleic acids are synthesized on the support and the synthesis steps include oxidizing a phosphite triester nucleic acid linkage to a phosphate triester nucleic acid linkage using a solution about 0.005 M to about 0.05 M iodine in a mixture comprising water and organic solvent. In another group of these methods a plurality of nucleic acids are synthesized on the support and the synthesis steps include oxidizing a phosphite triester nucleic acid linkage to a phosphate triester nucleic acid linkage using a solution comprising iodine and at least 4% by volume of water.
